Last winter my wife slid off the road in a nasty storm in her 99 sentra.

After we got it back from the collision people the horn doesn't sound when we lock the car with the remote.

I know you can change to programming to either honk or not, how do I change it back to honking when locked?

look in the manual of the car book. it should be there. i believe that you have to hold the lock button for like 5 sec. you might have to do it 3 or 4 times maybe. that should do it, that happened with my 2001 sentra, and that fixed the problem.

on my 99 you have to hold the lock and unlck buttons for like 5 seconds or something its a gxe
